Powerful jQuery Image Zoomer: Cloud Zoom

The plugin is unobtrusive and displays the zoomed version of the images:

near the thumbnail image

inside the thumbnail image (inner zoom)

when hovered.

It works in a "gallery mode" by default which automatically display a list images, shows the clicked one and can zoom to that image. This is very useful specially for product showcases (like in e-commerce websites).

The smoothness of the zoom effect, tint over the thumbnail or lens opacity can be totally customized and the plugin can be styled via CSS.
